Composite-Decorative Tiles with Granite
MetadataAfficher la notice complète
The paper presents the results of the authors’ scientific research on a composite material with polymeric matrix, hardened with rock particles. It was studied the influence of the quantity of the hardening phase on the compression resistance of the product. These weather resistant materials have a long period of ageing, a permanent finishing and require almost no maintenance. For the research was used granitee from the Măcin Mountains, Dobrogea România with greenish shade, which was crushed and then granulometric sorted. Granitee is an acid volcanic rock, with over 65% SiO2; it has granular structure and massive texture. Polyesteric thermorigid resin was used for the matrix. These resins can be characterized by: easy obtaining and accessibility of the raw materials, quick strengthening without side-off products, good chemical resistance at acids and alcohols. Composite samples were made through shaping in steel mould. After shaping and maturation, the samples were tried at compression.
